Used primarily in research as a potent and selective inhibitor of cyclin-dependent kinases (CDKs), particularly CDK2 and CDK9. It is employed in studies related to cell cycle regulation and transcription control in cancer cells. Due to its ability to induce cell cycle arrest and apoptosis, it serves as a valuable tool in oncology research for evaluating the effects of CDK inhibition on tumor growth and proliferation. Also utilized in the development of targeted therapies, especially in hematological malignancies and solid tumors. Its structure allows for modification to improve pharmacokinetic properties, making it a scaffold in designing new anticancer agents.
